cURL - sending array as post value

[Splash]

Hi all,

 

I'm trying to send some data to a remote domain but am having an issue with one of the variables being an array. The problem is that the preferences array loses it's individual values at the other end. Any idea what I'm doing wrong here?

 

 

$url = 'http://foo.com/';

	$params = array(
		'name' => ' Test',
                'age' =>  24,
                'preferences' => array(1,2,3,4,5,6)
	)

    $user_agent = "Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_POST,1);
    curl_setopt($ch, CURLOPT_POSTFIELDS,$params);
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);

if(curl_exec($ch) === false) {
	echo 0;
} else {
	echo 1;
}

curl_close ($ch);

Figured this out. Needed to do it as a string. e.g.

 

$url = 'http://foo.com/';

$params = 'name=test&age=24&preferences[]=1&preferences[]=2&preferences[]=3&preferences[]=4&preferences[]=5&preferences[]=6';

    $user_agent = "Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_POST,1);
    curl_setopt($ch, CURLOPT_POSTFIELDS,$params);
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);

if(curl_exec($ch) === false) {
  echo 0;
} else {
  echo 1;
}

curl_close ($ch);

For what it's worth, you can (likely) use the http_build_query function to make an array into the required string format.

 

$example = array('a' => 'apple', 'b' => 'banana');
$postfields = http_build_query($example);
echo $postfields;

 

Gives us the array formatted as a=apple&b=banana
